I got mine from eBay, quite cheap (£30) for a color calibrator, they are usually around £100+ even for a used one, without knowing that it's not going to work on my Win 8.1 laptop, I could't find much on how to make the Eye-One Display 2 work so I hope that this will help others like me.
It works fine on Windows 7 32/64 bit but it is not recognized on Windows 8 / 8.1 so this is how I've installed it:
Step 1 - from the X-Rite website you have to download the following:
the calibration software - Eye One Match 3 - http://www.xrite.com/i1display-2/support/d724 - this works on any windows version
the drivers pack - http://www.xrite.com/i1display-2/support/d768 - this is in fact for win XP to Vista but it worked on my laptop (win 8.1 64bit)
--CAUTION-- INSTALL DRIVER FIRST!! AND SOFTWARE AFTER
Step 2 - Unpack the driver pack, I've unpacked it on my desktop (right click on the zip archive - unpack, chose a location easy to access)
Step 3 - Connect the Eye One and go to Control Panel / Device Manager, you should see it in the list with a yellow triangle.
- Right click on it - Update driver software
Step 4 - Select Browse my computer for drivers and chose Let me pick from a list,
- Click Show all devices / Next / Have Disk / Browse and go to the location where you've unpacked the zip file.
- Chose i1_io2.inf and click Open and OK, it should look like this:
- Click Next and Close after the driver is installed
- It should appear installed in the Device Manager list
Step 5 - Install the downloaded calibration software - Eye One Match 3, it should ask for a restart after the install
Step 6 - Launch the application and follow the wizard in order to calibrate your display.
I hope this works for you, it worked on my laptop. I think it's a good option if you don't want to spend more on a new and updated device, it might work in the same way on a Mac OSX but I don't have one to test on.
One thing I don't know, if the calibration is accurate or not, maybe somebody can do crosscheck with a fully compatible device and let us know. It looks fine on my screen even if it's not the best quality display.
I could do with some feedback if it worked for you.
I hope this article will help!
UPDATE - Just updated OS to Windows 10, the calibrator still works fine, I haven't done a new install on Windows 10 but I guess is the same as on Windows 8 / 8.1. If anyone tried the install on Windows 10, please let me know.
UPDATE 2 - from comment - Apparently the've made a fix - not tested yet https://www.xrite.com/i1pro/support/d1398
